Introduction: Make Your Own NON Dead-Blow Hammer!

About: I've been making Instructables since I was 13. Now, I mostly make videos of my projects, however I'm still active here, so don't hesitate to reach out! Sick with a deadly disease called DIY-itis!

A Dead-Blow Hammer is a hammer that doesn't bounce back up when hit, and less force is required when using it, because of it's weight. This type of hammer also saves a lot of time and effort, when compared to a regular mallet (soft hammer).

Did you know you can make, and choose the exact weight that you want for your Dead-Blow Hammer with an old transformer?

In my last Instructable, I showed you how to make The Flat-Pack Bandsaw. Today, I'll show you how to make a Dead-Blow Hammer, made from almost entirely recycled and junk materials!

Let's get started!

(Warning: Use this Instructables' content at your own risk. If you decide to eat this hammer, do it at your own risk!)

Step 1: What You'll Need:

Hardware & Materials:

~1KG Transformer (From an old retractable bed)

2 Zip-Ties

Some soft Wood (From an old shipping crate)

16mm (Diameter) Metal Rod (From an old IKEA Lamp)

Chemicals & Adhesives:

Gorilla Tape

Tools (+Attachments):



3mm Drill-Bit

2 Clamps

Electric/Power Tools:


Circular Saw


Why: Because I don't have a Hydraulic Press! Ummm, No... :)

Recommended Safety Equipment: Earmuffs, Respirator, Safety Goggles,

Cost (for me): FREE!

Difficulty: Easy

Approximate Time: ~30 Minutes

Step 2: Cut the Wires Off of the Transformer

After choosing the transformer I wanted, I used a wire cutter to cut off the wires.

Step 3: Enlarge the Holes in the Transformer

I used a 3mm Drill-Bit to enlarge the holes that were in the transformer. I did this so the Zip-Ties would be able to fit in them (Next step).

If your transformer doesn't have these holes, I might be able to help you in the comment section :)

Step 4: Attach the Handle to the Transformer

I started by folding a small piece of Gorilla Tape, so it would act as double sided tape (And as a cushion between the transformer and the handle). After that, I Zip-Tied the handle tightly to the transformer.

Step 5: More Gorilla Tape!

I added a bit more tape to the top, even though it isn't really needed. It strengthens the connection a bit more, and makes it look better.

I can definitely tell you that this handle isn't going anywhere.

Step 6: Cut the Wooden Pad (cushion)

I decided that I want to add a small piece of wood, which acts as a cushion to both the object that is being hit, and the transformer.

I started by tracing the outline of the bottom of the transformer onto a piece of soft wood that I had previously clamped to the table, And then cut it out with my new horrible circular saw. It was a bit hard to saw off one part, so I plunged the saw, and then removed it by hitting it with the hammer.

Step 7: Glue the Wooden Pad Onto the Hammer

I thought I'd try hot glue as an adhesive for gluing the pad to the bottom of the transformer, and indeed, it (still!) hasn't failed!

I scratched the wood a bit, applied a generous amount of glue to one side of the pad, and clamped it as quickly as I could.

After the glue hardened, I applied more glue to the sides (the gaps)

Step 8: DONE! Dead-Blow Hammer VS. Computer Mouse

Ok, this was just for fun... :)

I wanted to test how strong this hammer was, even without applying a lot of force.

What you can see in the pictures is the before shot, and after (and after collecting all of the pieces that flew everywhere) smashing it to pieces.

Yes, it did that with one hit!
